CARPET-CLEANER.

S JPEGIFICATIQN '50 "fig: part of Letters Patent NO. 359,709, datedMarch 22, 1887.

Serial No. (No model.)

1'0 all 1U7L0722; it may concern.-

Be it known that I, EDWIN A. BURR, of the city of Auburn, State of NewYork, have invented certain new and useful Improvements inCarpctGlcaners, of which the following is a full and exact description,reference being had to the accompanying drawings, forming part of thisspecification, in which- Figure 1 is a side elevation of my improvedmachine; and Figs. 2 and 3 are end and side views, respectively, of thebrush.

The object of my invention is to keep acarpet-cleaning machine clearedof dust and dirt by causing a draft of air to pass through it, and tocause this draft of air by means of the revolution of the drum or cageitself. I no coinplish this result by means of the mechanisinhereinafter described.

A cage ordrum, A13 A B, of any of the various forms, prismatic orcylindrieahwhich are used in such machines, and provided with a slattedperiphery, is suspended to revolve upon its horizontal axis, Fig. 1, thedotted circles indicating the periphery of a cylindrieal cage or drum. Iinclose'such a cage or drum within a casing, F G F H which is ofsui'ticient size to permit of the drums revolution within the casingwith the wing-boards attached, which boards are hereinafter dc scribed.This casing F G F H is provided with the entrance and exit shafts D andE, and has doors F II opening into it, through which access is had tothe drum within. To the periphery of the. drum and radially thereto Iattach the wing-boards O G rigidly, and in number from three or four toeight, as it is desired to create a draft ofair more or less strong bythe revolution of the drum.

If the d rum has inwardlyextending sides or is prismatic in form, thesewing-boards are preferably secured, as shown, to some intermediate pointin such sides and extend from one end to the other of the drum. The drumthen being revolved in the direction indicated by the arrows 1) b, astrong draft will be caused thereby into the shaft D and out at E, asindicated by the arrows at a and a c. In place of one of the boards 0 C,I hinge a brush, d, to the periphery of the drum and support it by thesprings e 6, so that while. it brushes the interior of the casing it mayyield, if necessary, upon its hingesff, Figs. 2 and 3. By this means anylodgment of dust or dirt is prevented in the operation of the machine;

What I claim as new, and desire to secure by Letters Patent, is-

1. In a carpet-cleaner, the revolving drum provided with wing-boards GC, secured radially to its periphery.

2. In combination with the revolving drum of a carpet-cleaner, providedwith radial wings G C, the casing F G F H, provided with entrance andexit shafts D and E, substantially as described.

3. In combination with the revolving drum of a carpeteleaner, the casingF G F H and brush (1, secured to the drum and revolving therewith.

4. In combination with the revolving drum of a carpet-cleaner and itseasing F G F H, a brush, (Z, .hinged thereto, supported by the springs ee.
